FADEC’s behavior regarding predicting exceedances for startup versus shutdown is which of the following?

• A. It Predicts Exceedances For Shutdown
• B. It Predicts Exceedances For Startup
• C. It Waits For An Exceedance To Occur And Does Not Predict Shutdown Exceedances
• D. It Always Aborts On Start

Answer: (C)

FADEC protection is reactive to real-time conditions rather than forecasting problems. It monitors parameters as the engine operates and will intervene if an exceedance actually occurs. It does not preemptively predict that a shutdown exceedance will happen; instead, it waits for a true exceedance to occur before taking protective action. That’s why the correct description is that FADEC waits for an exceedance to occur and does not predict shutdown exceedances.
